Fires have also been started in complexes at 100 and 300 Cold Springs Road. Last Wednesday, firefighters responded to a dumpster fire at 100 Cold Springs Road.

Residents are at their wits' end, according to a woman who lives in one of the towers.

``Nobody trusts anybody anymore,'' said the woman, who asked not to be identified.

The woman said management workers put two memos at residents' doors on Thursday. One memo said that locks at the complex will be changed next week, while the other said storage locks have already been changed.

Residents must set up appointments to get into the storage areas, which are on each floor.

Most of the fires have been started in dumpsters found in the bottom floor, but at least three others were inside the storage areas.

No one has been injured in the fires but some residents have lost personal property in the storage areas. Police continue to investigate the fires.
